UPS, USPS testing new returns program - Atlanta Business Chronicle United Parcel Service Inc. has teamed with the U.S. Postal Service for a five-month pilot program that aims to make returning packages a bit easier. The Atlanta-based package shipping giant said Tuesday it will test UPS Returns Flexible Access -- a returns service with a few pre-selected retailers that allows consumers to return items shipped through UPS by placing them in their own mailboxes for pickup by the U.S. Postal Service. Consumers also can drop the package off at their local post office or in postal collection boxes. A UPS driver will then pick up the package and send it back to the retailer through the UPS (NYSE: UPS) ground network.
